I CANT DO THIS :(

My 19 month old is a nightmare. He does not listen to me, he gets into EVERYTHING.... bedtime is a gong show... I'm overdue with our second baby right now and I'm losing my freaking mind I don't know how I'm going to handle this. my husband and I are not getting along because the stress is driving both of us nuts. I can't believe I'm going to have a newborn when I can't even handle my first child. my heart is breaking right now I don't know what to do. I freaking love my first born to death but he is driving me up the wall :(😩😠😔
